Extra Tips for Air Conditioning Preventive Maintenance

While the air conditioning preventative maintenance checklist above is a useful resource on its own, we have a few extra tips for you that are just as helpful. These involve preventing heat buildup and overcooling triggers.

Heat buildup in your home can cause your air conditioning unit to run more than it needs to.  Additionally, there are a few ways in which your thermostat can become triggered to turn on and expend extra energy.

This will increase your energy costs and perhaps even decrease the lifespan of your system.

Below, we put together another checklist of actions you can take to prevent heat buildup and prevent your thermostat from overcooling your home.

  • Make sure attic is properly ventilated as to prevent heat build-up
  • To prevent triggering your thermostat to overcool your home, move any heat-producing equipment (TV’s, lamps, etc.) away from a wall-mounted thermostat
  • Keep curtains and blinds closed during the hottest time of the day, and when you’re not home
  • Make sure your thermostat is located away from windows and doors
  • Research your roofing material to make sure it doesn’t absorb so much heat from the sun that it’s making your AC work in overtime
  • Consider how well your home is insulated. Not only will this prevent cool air from escaping in the summer, it will also prevent heat from escaping in the winter
  • If you decide to improve your home’s insulation or roofing situation, use to find a contractor in your area
